Kap test difficulty?

Hi, crying a bit but I took kap’s new for 2026 test 8 and scored 511, 514 on new test 9. But then I took kap’s old test 8 today and my score dropped like embarrassingly low. The test did feel harder but holy crap I feel like my confidence plummeted because I thought I was finally doing better and then I got humbled. Idk if this is normal or if anyone else had a similar experience but I can’t find any new posts about it. Should I just call it quits or something 🫡
